Revision 7993ba43db1c07245ada067791f91dbf018095ac authored by Avi Kivity on 26 January 2007, 08:56:41 UTC, committed by Linus Torvalds on 26 January 2007, 21:50:57 UTC
Check pte permission bits in walk_addr(), instead of scattering the checks all over the code. This has the following benefits: 1. We no longer set the accessed bit for accessed which fail permission checks. 2. Setting the accessed bit is simplified. 3. Under some circumstances, we used to pretend a page fault was fixed when it would actually fail the access checks. This caused an unnecessary vmexit. 4. The error code for guest page faults is now correct. The fix helps netbsd further along booting, and allows kvm to pass the new mmu testsuite.
